i never looked back here at this post. except no, dirt will get onto your coilovers in ike a week of having them installed. making it hard to raise or lower your coilovers. The one hand advertisements bs in my opinion. You need someone to step down on your rim to loosen up the coilover from the shock. Once its really loose you can turn it. its easy i guess but you need a friend their unless your ridges on your coilovers are perfectly clean
